200 9 x 12 white mailing envelopes (Kensington)

We received a box of very nice quality white envelopes, 9 x 12, printed with a company's logo in the return address corner. We covered the printing with a blank label (see picture). We've used all we need and there are 200 or so waiting for the next person. Porch pickup. Please state a day and a 2-hour time window for pickup.
